Dynamic DropDowns

I’m trying to create a dynamic dropdown where one drop down is dependent on the other.

I want to make counties available in one dropdown based on the state selected in another.

I’ve read everything I can find on the subject and have tried at length everything I’ve found,
but nothing seems to be working.

Check carefully this forum post which has an example and you should understand how it works.
In addition there are other posts that explain the same.


B) I am looking to create close to the same things with thousands of fields i will need to get down the process before i add these fields.

something like this
